{"Image DocumentName": "Thus for a field due to a (point or spherical) mass M:", "Image ImageDescription": "So ... E.g. Calculate the potential of a 5kg mass at a point 200km above the surface of Earth. What would be the potential of a 10kg mass at the same point? ( G = 6.67 \uf0b4 N m2 kg-2 , mE= 6.0 \uf0b4 1024 kg, rE= 6.4 \uf0b4 106 m ) The gravitational potential at a point in a field is defined as the work done per unit mass in bringing a point mass from infinity to the point in the field. V = Ep = - GMm. m r m. V = Gravitational potential (Jkg-1) V = - GM r.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
